(Cl. lill-8) Claims.

This invention relates to lncinerators and more particularly to the automatic control of incinerators of a type adapted for domestic use.

One of the objects of the invention is to provide an incinerator in which the supply of heat is regulated in accordance with the Weight of the material to be incinerated.

Another object of the invention is to provide an incinerator in'which the material is supported by a movable container part connected to the fuel control valve to regulate the supply of fuel in accordance with the position of the container part. Preferably, the container part is pivotally supported at one end and is suspended on springs at its other end, yieldingly to balance the Weight of the material carried thereby.

Still another object of the invention is to provide an incinerator in which the supply of heat is varied between maximum and minimum limits in accordance with variations in the amount of material to be incinerated.

The above and other objects, advantages, and novel features of the invention will be apparent from the following description when read in connection with the accompanying drawing,in which the single ligure is a perspective view, With parts broken away, of an incinerator embodying the I invention.,

The illustrated incinerator comprises an outer casing I of generally rectangular shape, having a filling opening in its top closed by a hinged cover 2. An ash drawer 3 is slidably mounted in the bottom of the casing to receive ashes, and may easily be removed when desired.

Within the upper part of the casing, lthere is mounted a container for garbage, trash, and like material to be incinerated. As shown, the container is formed with an upper portion, including rectangular Walls 4 fixedly mounted in the upper part of the casing and spaced from the sides thereof. The space Within the walls 4 communicates with a flue 5, which extends through one side wall of the casing, a screen 6 being mounted in the container to prevent entry of large particles of material-into the flue.

The open bottom of the container walls 4 is closed by a lower container portion, including side walls 'l telescopically surrounding the walls 4, and a V-shaped bottom formed by a solid bottom wall 8 and a screen 9. The screen 9, as shown, is slidably supported between flanges formed on the sides 'I and has a shaker bar ID connected thereto and extending through the casing. By this means the screen may be shaken periodically to cause ashes supported thereon to drop through into the. drawer 3. l

The lower container portion is adapted to be movably supported in the casing, and for this purpose is formed at one end with lugs or ears II, carrying adjustable screws I2, which rest on a flange or angle-iron I3 secured to the casing.

This construction provides a pivotal support for one `end of the container bottom portion, and the opposite end of this portion is suspended on tension springs I4, connected to an angle-iron I5',

carried by one of the fixed container walls 4.. Due to this construction, the lower container portion is adapted to move about its pivotal supe port in response to the weight of material to be incinerated in the container, the springs I4 serving as a balance against which the weight of the material acts.

Below the screen 9, there is lxedly mounted on the casing a fluid fuel burner I6, shown as cornprising a gas pipe discharging below the screen 9. Flow of fuel to the burner I6 is controlled by a valve I'I iixedly carried by the casing I, and adapted to regulate the fuel supply between minimum and maximum limits. The valve I'i is regulated by the connection I8 to a lug or ear I9 4rigidly carried by the solid botto-m portion B of the container. In this way,'movements of the container bottom portion regulate vthe valve I'I to increase or decrease the fuel supply, as required. In operation, with the container empty, the springs I4 will raise the bottom portion thereof, pulling on the connection I8 to close the valve I1. to its minimum opening. This minimum opening may provide a relativelysmall flame in the neighborhood of 400 B. t. u. per hour. As material is loaded into the container, the bottom portion thereof will move downwardly to a greater or less extent about the pivotal mounting I2-I3, thereby pushing on the connection I8 to open the valve I 'I and increase the fuel supply. The valve is preferably so adjusted that in its maximum open position, which it will occupy when the container is substantially full, it will supply fuel to the burner at the rate of approximately 2500 B. t. u. per hour per bushel of material to be incinerated. It will be understood that the springs I4 may be adjusted to regulate the valve Il in any desired manner. With this construction, the burner is operating continuously, and due to the relatively low rate of heat supplied, the material will be incinerated relatively slowly. As the material is burned out, the ash drops through the screen 9 into the drawer 3, and decreases the weight acting on the lower container portion so that the springs I4 tend to raise this portion and reduce the valve opening. The supply of fuel is thus automatically regulated in accordance with the demands of the incinerator.

While one embodiment of the invention has been shown and described in detail, it will be understood that this is illustrative only, and is not to be taken as a denition of the scope of the invention, reference being had for this purpose to the appended claims.
